The separate bed deioniser uses an ion exchange cartridge to filter the water before it enters the battery. Cartridges can be discarded when replacement is necessary.
The low pressure bypass ensures that the deioniser will provide enough pressure and flow to operate your SPW system, even if you forget to change out an old cartridge.
For batteries equipped with Millennium SPW or Pro-Fill systems.
(SPW system must have BA-QDV-500 or BA-QDV-505 Quick coupler).
